Two hours later, I received a text message from tenant stating that he hired someone, paid $430 already and they are coming before 6pm. 

The second way you are basically get hired into a position by your own company as a mid management.

If not, hire a professional architect or floor plan designer, or use tools like RoomSketcher, MagicPlan, or Matterport to create them.

If so, as mentioned above, I would probably hire a PM if you do not want to run it yourself. 

The rep says that evictions only happen 3% of the time.

You cannot afford to waste time.Just make sure your numbers are accurate otherwise you can create a bad rep among real investors. 

You can track income and expenses consistently using software or spreadsheets.As you scale, if bookkeeping isn't fun, consider hiring a bookkeeper for a couple hundred bucks per month.

It is important that you hire professionals who have experience working with foreign investors.

So there is that rep out there. 

At that point, you just need deal flow - perhaps that means its time to hire or paratner with an acquisition manager to help you find and close deals - a good realtor can step in here as well
